Ovulation bleeding? HELP?!

Adriana

I am so new at this and I don’t know what is going on. I’ve never had this before! My periods are regular and when I wiped this morning there was brown/red discharge, I’ve been off my period for 5 days now. Does anyone know what this could be? Chart of my cycle

And I’ve been feeling super nauseous! I don’t know what’s going on!
